A Powerful Plaything

Soccer_BallTwo Harvard undergraduate students, Julia Silverman and Jessica Matthews, have come up with a way to harness the kinetic energy of a moving soccer ball and store it as electric current in a battery inside the ball. The invention, called sOccket, collects enough energy in 15 minutes of play to power a typical LED lamp for three hours. The device sports its own power outlet to retrieve the juice inside. Today’s sOccket is designed to last for a year or longer; researchers are studying its larger potential.
